Extensive variability in the gut microbiome of a highly-specialized and critically endangered lemur species across sites.

Deforestation continues to jeopardize Malagasy primates as viable habitats become smaller, more fragmented, and more disturbed. This deforestation can lead to changes in diet, microhabitat, and gene flow between populations of endangered species, and it remains unclear how these changes may affect gut microbiome (GM) characteristics. The black-and-white ruffed lemur (Varecia variegata), which is among Madagascar's most threatened lemur species, provides a critical model for understanding the relationships between historical and on-going deforestation (habitat disturbance), feeding ecology, and GM composition and diversity.
